Hello Steve and welcome to the Disney Parks Moms Panel where as the current UK Mum on the Panel it's my pleasure to assist another Guest from the United Kingdom with their jolly holiday plans to visit the magic of Walt Disney World Resort.
I'm super excited to know you're planning on an almost 3 week stay in the sunshine State of Florida with a split stay at Walt Disney World Resort at the beginning and end of your holiday; it certainly sounds practically perfect in every way to me!
You'll be making a great choice by opting for the UK exclusive 21 day
Ultimate Ticket as this provides Guests with the
ultimate in flexibility and gives unlimited access into all 4 Disney Theme Parks, 2 Water Parks, ESPN Wide World of Sports Complex and much more besides. I'm happy to share that at present 21 day Ultimate Tickets expire 21 days from their 1st day of use which means you shouldn't have any issues when using them at either the beginning or end of your wonderful stay.
To help bring the enchantment of your Disney trip even closer why not check out this

Have a great Disney day.
